ABSTRACT
This paper analyzes the relationship between microfinance and poverty reduction
in Vietnam. The study tests the hypothesis that access to microfinance and household
economic welfare are positively related. While literature has shown that microfinance is
good for microbusiness, the empirical findings vary greatly as a result of the various
methodologies used to assess the impact of microfinance. In measuring household
economic welfare, this paper uses expenditure indicators, including household per capita
real expenditure, per capita real food expenditure and per capita nonfood expenditure.
Access to microfinance is measured as the total amount of household borrowing.
The study uses cross-sectional data from Vietnamese Household Living Standard
Surveys in 2008 (VHLSS2008), a national survey of 9,189 randomly selected
Vietnamese households to derive empirical evidence. This paper found that household
credit has a significant and positive relationship with household per capita expenditure
and per capita nonfood expenditure. Moreover, household credit has a greater influence
on poor households, in comparison with better-off households. The relationship between
iii
household borrowing and per capita food expenditure, however, turns negatively. These
findings confirm that providing microfinance to the poor is an effective policy tool to
reduce poverty. Yet, its modest marginal impact suggests that poverty alleviation
programs need to refocus their attention on enhancing the efficiency and diversification
of microfinance activities.

I. INTRODUCTION
There are more than 1.2 billion people around the world living in extreme
poverty, or less than $1.25 a day (World Bank data 2010). Fighting against poverty has
thus become an urgent task for every nation, particularly developing ones.
One cause of poverty observed in developing countries is the credit constraint
imposed on the poor. Coleman (1999) described this situation as a poverty trap: “The
poor often find themselves in a vicious circle: producing at a subsistence level makes it
difficult to accumulate savings or other assets, thus making it difficult either to invest in
productive resources or to gain access to credit in formal capital markets, resulting in low
productivity and continued poverty”. Therefore, providing cheap credit to the poor, or
microfinance1 has been considered as a tool for economic development and poverty
reduction. In the last decades, it has evolved from a grassroots movement to a global
industry with more than 190 million clients (Ledgerwood, 2013). The importance of
microfinance in socio-economic development actually has been confirmed in practice by
the United Nations’ decision to name 2005 as the International Year of Microfinance. In
2006, the Nobel Peace Prize was given to Muhamas Yunus, founder of the Grameen
Bank for their pioneering efforts to provide microfinance to the poor in Bangladesh.
In Vietnam, microfinance is also viewed as a priority of poverty alleviation
programs. About 72 percent of the population lives in rural areas, of which 94 percent are
poor. Agriculture remains the key economic sector, with 54 percent of the labor force
working in agriculture (World Bank, 2011). Thanks to the government policy,
microfinance has developed rapidly in recent years. Vietnam currently has 52

microfinance institutions, serving about 12.3 million clients or 14 percent of the country’s
population (Nguyen et al, 2011).
Since microfinance has been delivered on large scale as a policy tool to alleviate
poverty and promote the development of small enterprises, evaluating its impact on
poverty reduction is necessary to ensure that limited resources have been spent
efficiently. Hence, this paper will examine the association between microfinance and
poverty alleviation. Specifically, the paper tries to answer whether and to what extent
credit access has helped to increase household economic welfare in Vietnam.
II. EXAMINING THE LITERATURE
A. Effectiveness of microfinance
The effectiveness of microfinance in reducing poverty in fact has been widely and
rigorously debated over the last few decades. On one side are researchers insisting that
microfinance has strongly positive impacts (Hossain, 1988; Khandker, 1998; Pitt and
Khandker, 1998; Khandker and Faruqee, 2003; Khandker, 2005). For example, one of the
most-respected studies conducted in Bangladesh by Khandker (2005) found that each
additional 100 taka of credit to women increased total annual household expenditures by
more than 20 taka. His findings also showed that among program participants who had
been members since 1991/92 until 1998/99, poverty rates declined by more than 20
percentage points – roughly 3 percentage points per year. Some other researchers
postulated that microcredit brought wider social impacts in terms of women’s
empowerment, increase of contraceptive use and improvements in children’s nutrition
and overall health (Hashemi et al, 1996; Pitt et al, 2003).

On the opposite side are researchers who concern that microfinance may bring
about negative impact on the poor (Adam & von Pischke, 1992; Kondo, 2007; Roodman
& Morduch, 2009). Kondo (2007) studied a microfinance operation in rural Philippines,
finding that the poorest borrowers actually see negative effects such as credit dependency
and cyclical debt. Moreover, a number of studies found that several microfinance
programs did not help the poorest, as is so often claimed (Hulme and Mosley, 1996;
Coleman, 2006; Kondo, 2007). For example, Coleman (2006) examined two micro-
lending programs in northeast Thailand and found that they were more likely to reach
relatively wealthy borrowers than the target group of the “poorest of the poor”. These
studies raise concern that microfinance programs might not reach their intended
recipients.
The debate on the effectiveness of microfinance on poverty reduction has been
heated again when the first studies using the randomized controlled trial methodology
(RCT) were released in 2009. They showed that over a relatively short time period,
microfinance had a number of positive impacts on the lives of poor clients, including
increases in business investment and expenditures for women, supporting the creation
and expansion of small businesses and increases in business profits (Banerjee et al, 2009;
Dupas and Robinson, 2009; Karlan and Zinman, 2010). However, they did not find
evidence of overall effects on broader measures of poverty and social well-being.
While studies have shown that the impact of microfinance on poverty alleviation
is ambiguous and depends on certain circumstances, there is evidence from various
studies, which use a variety of methodologies across different settings, suggesting that
microfinance is good for microbusinesses (Odell, 2010). By providing credit to the poor,
